Mitutoyo 337-303 Digimatic Tubular LCD Inside Micrometer, Extension Rod Type, 8-40" Range, 0.0001" Graduation, +/-0.00092" Accuracy, 6 pcs Extension Rods
The 337 series Digimatic tubular LCD inside micrometer includes a set of solid extension rods to help provide durability when measuring inside dimensions of cylinders, rings, and parallel surfaces. It has a single-value LCD readout that displays in inch and metric units with resolution to 0.00005” (0.00mm), and Statistical Process Control (SPC) data output to transmit results to a computer or external device. The output jack transmits SPC results to a computer through an interface cable (sold separately).
The micrometer’s electronic microprocessor can hold measurements at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading. The electronics housing has an Ingress Protection 65 (IP65) rating, which means that components are resistant to penetration by dust and debris, and resistant to penetration by liquids and coolant up to the force of a low-pressure (to 30 kilonewtons/meter-squared) water jet. The measuring faces are carbide-tipped for wear resistance. The micrometer includes, and is powered by, a single SR silver oxide battery, and comes with a wooden case for storage.
Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
